Black-eyed Susans bring a cheerful, slightly wild personality to the garden. Their golden petals seem to shout, “Summer is going wonderfully!” even when the lawn is crispy and the mosquitoes have declared ownership of the patio. Fortunately, you can preserve some of that sunny color by drying the flowers for arrangements, wreaths, pressed art, seed saving, and seasonal crafts.
Drying Black Eyed Susans is not difficult, but choosing the right method matters. Their broad yellow ray petals are relatively thin, while the dark center cone is thick and moisture-rich. That uneven structure can make a whole flower curl, droop, or dry poorly when treated like an ordinary bouquet flower. Air drying works best for rustic arrangements and seed heads, silica gel is better for maintaining the flower’s shape and color, and pressing is most successful when you modify the thick center or use individual petals.
This guide explains how to dry Black Eyed Susans using four practical methods, how to prevent mold and petal loss, and how to store the finished flowers so they remain attractive rather than becoming a box of mysterious yellow crumbs.
Understanding Black-Eyed Susan Flowers
Black-eyed Susan commonly refers to several Rudbeckia species and cultivars, including Rudbeckia hirta and Rudbeckia fulgida. The familiar bloom is a composite flower head with yellow or orange-yellow ray florets surrounding a raised, dark brown central disk. Depending on the type, the blooms may be roughly 2 to 4 inches wide and appear from early or midsummer into fall. Many varieties also make dependable cut flowers.
The central disk is the main drying challenge. It contains substantially more plant material than the petals, so it loses moisture more slowly. If the flower is packed into a humid container or hung in a large bundle, the petals may feel dry while the cone is still holding enough moisture to encourage mold.
When to Cut Black Eyed Susans for Drying
Harvesting at the right stage gives you stronger petals, brighter color, and fewer disappointing results.
Choose freshly opened flowers
For decorative drying, select flowers that have opened fully or are just short of full maturity. The petals should be brightly colored, firmly attached, and free from brown edges. Avoid flowers that have already started dropping petals or producing visibly mature seeds.
Drying preserves the condition of a flower; it does not improve it. A bloom that looks exhausted in the garden will not wake up during drying and begin a glamorous second career.
Harvest after the dew has dried
Cut the stems on a dry day after morning dew has evaporated. Flowers should be completely dry on the surface. Rain-soaked or dew-covered blooms introduce extra moisture, increasing drying time and the chance of discoloration or mold. Iowa State University guidance similarly recommends harvesting flowers at peak quality when no water or dew remains on the blossoms.
Cut more flowers than you need
Not every Black-eyed Susan will dry perfectly. Some petals may curl, loosen, or develop uneven color. Harvesting a few extras gives you enough successful blooms for your project without requiring an emergency return to the garden three weeks later.
Tools and Materials
You will need only the materials required for your chosen drying method:
- Clean, sharp pruning shears or garden scissors
- Rubber bands, string, or floral wire
- A dark, dry, well-ventilated room for air drying
- Flower-drying silica gel and an airtight container for shape preservation
- Absorbent paper, cardboard, and heavy books or a flower press
- Paper bags or envelopes for drying and saving seed heads
- Labels and a permanent marker
- An airtight storage box for finished flowers
Inspect each flower before drying. Remove insects, damaged leaves, and any petals that are already bruised. Do not rinse the flowers unless absolutely necessary. Added water is the guest nobody invited to a drying project.
Method 1: Air Drying Black Eyed Susans
Air drying is the simplest and least expensive method. It creates a natural, rustic appearance that works well in fall bouquets, cottage-style arrangements, wreaths, and mixed dried displays. However, the flowers will usually become darker, more curled, and less dimensional than silica-dried blooms.
Step 1: Prepare the stems
Cut stems approximately 8 to 12 inches long. Strip away most or all leaves because foliage retains moisture and can slow the process. Discard any stems showing disease, spots, or soft tissue.
Step 2: Make small bundles
Gather three to five stems and secure them with a rubber band or string. Small bundles permit better airflow than one enormous bouquet. Remember that stems shrink as they dry, so rubber bands often hold more securely than loosely tied string.
Step 3: Hang the flowers upside down
Hang each bundle in a dark, dry, warm, and well-ventilated location. A closet, spare room, or dry basement area may work, provided humidity is low. Avoid bathrooms, damp garages, sunny windows, and laundry areas where steam regularly appears.
Darkness helps reduce fading, while airflow removes moisture and discourages mold. General extension guidance recommends hanging plant material in a very dark, dry environment, with air-drying periods commonly ranging from about two to four weeks depending on the plant, humidity, and stem thickness.
Step 4: Check the flowers regularly
Begin checking after 10 to 14 days. The stems should feel rigid, the cones should be dry, and the petals should have a papery texture. Thick centers may require another week or more. Do not pack the flowers away while the cones still feel cool, flexible, or slightly soft.
Step 5: Protect the finished flowers
Handle air-dried Black-eyed Susans by their stems rather than their petals. A light application of a floral sealant may reduce shedding and moisture absorption, but test it on one bloom first. Heavy spraying can darken petals or leave them looking unnaturally glossy.
Method 2: Drying Black Eyed Susans With Silica Gel
Silica gel is generally the best choice when you want the flower heads to remain fuller and more colorful. The granules surround and support the petals while drawing moisture from the plant tissue. University extension recommendations commonly place silica-gel drying time between three and eight days, depending on flower thickness.
Step 1: Shorten the stems
Cut each stem approximately 1 to 2 inches below the flower head. Long stems are difficult to bury without using an enormous container and a financially alarming quantity of silica gel. You can attach floral wire after drying if longer stems are needed.
Step 2: Add a base layer
Pour about 1 inch of flower-drying silica gel into the bottom of an airtight container. Use a container deep enough to cover the center cones completely without crushing the flowers against the lid.
Step 3: Position the blooms
Place the Black-eyed Susans face up on the silica layer, leaving space between them. Face-up positioning makes it easier to preserve the natural spread of the petals. For unusually curved blooms, experiment with placing one flower face down to see which orientation works better for that cultivar.
Step 4: Cover the flowers carefully
Slowly pour or sift silica gel around the outside of each bloom. Use a spoon to guide granules between the petals without bending them. Continue until the flowers are completely covered.
Do not dump the entire container of silica onto the flowers as though you are burying treasure before pirates arrive. Gradual coverage gives the petals support while allowing them to retain their arrangement.
Step 5: Seal and label the container
Close the lid tightly and write the drying date on a label. Silica gel must be used in an airtight container; otherwise, it absorbs moisture from the surrounding air instead of efficiently drying the flowers.
Step 6: Check after four days
Black-eyed Susans often require approximately four to seven days because of their raised center disks. Check one flower carefully. It should feel dry but not extremely brittle. A flower removed too early may droop, while one left too long can become fragile and shatter easily.
Step 7: Remove the gel
Tilt the container and gently pour away most of the silica. Lift each bloom by its short stem and remove remaining granules with a soft artist’s brush. Support the petals from underneath while cleaning them.
Method 3: Pressing Black Eyed Susans
Pressed Black-eyed Susans can be used in framed botanical art, greeting cards, bookmarks, resin crafts, and handmade paper. However, the thick center cone makes the complete flower difficult to press evenly. University of Georgia teaching material identifies Black-eyed Susan as one of the thick-centered flowers that is not ideal for ordinary whole-flower pressing.
Option 1: Press individual petals
Remove the yellow petals and arrange them between sheets of absorbent paper. You can press the cone separately or omit it and create a reconstructed flower later. This method produces cleaner, flatter results.
Option 2: Reduce the flower’s thickness
Use a sharp craft knife to carefully slice away part of the back of the center disk. Work slowly and protect your fingers. The goal is to reduce bulk without separating the petals from the flower head.
Option 3: Split the flower vertically
Cut the flower head in half through the cone and press the halves as botanical specimens. The result is less traditional but visually interesting, especially in educational displays or nature journals.
How to press the prepared flowers
- Place the flower or petals between two sheets of absorbent paper.
- Put the paper between pieces of cardboard.
- Insert the bundle into a flower press or beneath several heavy books.
- Keep it in a dry location for two to four weeks.
- Replace damp paper during the first few days if necessary.
Do not repeatedly open the press to check your progress. Moving flowers before they have dried can wrinkle petals, smear plant pigments, or cause the arrangement to fall apart.
Method 4: Drying Black-Eyed Susan Seed Heads
Black-eyed Susan seed heads are excellent for rustic decorations, winter arrangements, and seed collection. They also provide food for birds when left standing outdoors, so consider harvesting only part of your crop. Illinois and NC State extension resources recommend leaving some Rudbeckia seed heads in the garden for winter texture, self-seeding, and wildlife.
For decorative seed heads
Wait until the yellow petals have fallen and the center cones are dark brown and firm. Cut long stems on a dry day, bundle them loosely, and hang them upside down in a ventilated room for approximately two weeks. Once completely dry, add them to wreaths, dried grass arrangements, or minimalist winter bouquets.
For collecting seeds
- Allow the cones to mature and dry on the plant as much as weather permits.
- Cut the stems and place the heads upside down in a paper bag.
- Keep the open bag in a dry, ventilated room for one to two weeks.
- Rub or shake the cones to release the seeds and chaff.
- Separate the seeds as thoroughly as practical.
- Place them in labeled paper envelopes.
- Store the envelopes in a sealed container in a cool, dark, dry place.
Thorough drying is essential before seed storage. Silica-gel packets can be placed in the outer storage container to control humidity, but keep the packets separate from loose seed. Extension guidance from Iowa State, Minnesota, and Oregon State emphasizes cool, dry storage and the use of sealed containers or desiccants to prevent moisture damage.
Common Drying Problems and How to Fix Them
The petals turned brown
The flowers may have been harvested too late, exposed to sunlight while drying, bruised during handling, or dried too slowly. Choose fresher blooms and move the next batch to a darker, less humid location.
The center developed mold
The flower probably contained surface moisture, the room was too humid, or the bundles were too large. Discard moldy material rather than placing it near healthy dried flowers. Start again with dry blooms, smaller bundles, and stronger airflow.
The petals fell off
Overmature flowers shed petals more readily. Harvest earlier, handle the flowers by their stems, and consider silica gel instead of air drying. Silica supports the petals while they lose moisture.
The flowers became extremely brittle
They were probably dried too long or stored in excessively hot conditions. Reduce the drying time for the next batch and begin checking silica-dried flowers after four days.
The yellow color faded
Some fading is natural, especially during air drying. Direct sunlight accelerates color loss. Silica gel and dark drying conditions generally preserve color better than hanging flowers in a bright room.
How to Store Dried Black Eyed Susans
Display dried flowers away from direct sunlight, cooking steam, bathroom humidity, and heating vents. For longer storage, place the flowers in a rigid box with acid-free tissue paper. Do not compress the petals.
Add a small desiccant packet to the box in humid climates, but do not allow it to rest directly against the flowers. Label the container with the flower name and drying date. Check stored arrangements periodically for condensation, insects, or mold.
Even well-dried flowers are not permanent. Their colors will gradually soften, and the petals will become more delicate. Treating them gently can extend their decorative life for many months and sometimes longer.
Practical Experiences From Drying Black Eyed Susans
A typical first attempt at drying Black-eyed Susans often begins with optimism, a large bouquet, and the assumption that hanging everything from one hook will be perfectly adequate. A week later, the outside flowers may look dry while the centers of the inner blooms remain soft. This is the point when most people discover that airflow is not a decorative suggestion; it is the entire operation.
The most useful lesson is to divide the harvest into small test batches. Hang several flowers in bundles of three, place a few in silica gel, and press a handful of petals. This simple comparison shows what each method actually produces. Air-dried blooms usually develop a moodier, antique appearance. Their yellow petals may narrow, twist, and darken slightly, but the resulting flowers look wonderful beside wheat, ornamental grass, dried yarrow, and seed pods.
The silica-gel batch normally creates the biggest surprise. The blooms emerge looking much closer to their fresh form, especially when the granules have been poured slowly around each petal. The temptation is to uncover them every day, but patience produces better results. Opening the container repeatedly introduces humid air and disturbs the support around the petals. Checking one bloom after four or five days is more sensible than conducting a daily floral inspection worthy of airport security.
Another practical lesson concerns flower maturity. A bloom that has been open for a long time may look beautiful in the garden, yet its petals can detach during cleaning. Flowers harvested shortly after opening are usually sturdier. They also tend to have fewer insect-damaged edges. Cutting extra stems is useful because even careful drying produces some imperfect flowers.
Pressing demonstrates why the central cone needs special treatment. A complete flower placed directly inside a heavy book can create a thick lump that prevents the surrounding petals from drying evenly. Removing the petals or trimming the back of the cone gives a flatter result. Individual petals are particularly useful for cards and botanical collages because they can be arranged into new flower shapes after drying.
Seed heads offer the easiest and most forgiving experience. Once mature cones are dry, they retain a strong architectural shape and rarely require perfect petals. Placing them in a paper bag also captures loose seeds that would otherwise scatter across the floor. A paper bag is preferable to a sealed plastic bag during the final drying stage because it allows moisture to escape.
Humidity can change the entire outcome. A technique that works quickly in an air-conditioned room may fail in a damp garage. When flowers remain flexible after two weeks, moving them to a drier indoor location is usually more effective than simply waiting another month. A small fan can improve circulation, but it should move air around the flowers rather than blow directly at them and launch the petals across the room.
Finally, successful drying is easier when the intended project is chosen before harvesting. Long, straight stems are valuable for bouquets. Short-stemmed, flawless blooms are ideal for silica gel. Mature cones belong in seed-saving bags or winter arrangements. Matching the flower to the method reduces waste and produces a more polished result.
Conclusion
Learning how to dry Black Eyed Susans allows you to preserve their warm summer color for arrangements, crafts, seed saving, and seasonal decorations. Air drying is economical and ideal for rustic bouquets, while silica gel provides better shape and color retention. Pressing works best with petals or modified flower heads, and mature seed cones can be dried for both decoration and future planting.
The most important rules are simple: harvest healthy flowers on a dry day, give them enough airflow, keep them away from direct sunlight, and make sure the thick centers are completely dry before storage. Follow those steps, and your Black-eyed Susans can continue brightening the house long after the garden has traded its summer wardrobe for bare stems and suspicious-looking mulch.
Note: Dry Black-eyed Susans discussed in this guide are intended for ornamental crafts and seed collection. Do not use flowers for food, tea, cosmetics, or medicinal preparations unless their identity, growing conditions, and safety have been verified by a qualified source. Collect wildflowers only where harvesting is legal and permitted.
